This insert carries the KCP25B grade with a multilayer MTCVD coating stack of TiCN, Al2O3, and TiOCN, delivering moderate wear resistance and toughness suited to steel, cast iron, and aluminum workpieces. The 80-degree diamond (rhombic) shape provides a strong cutting geometry with a neutral hand orientation. It measures 12.90 mm (0.5077 inches) in length with a 0.5-inch inscribed circle and a 1\/64-inch (0.0156-inch) corner radius. Tooling engineers and CNC machinists specify this insert for medium machining chip-breaker applications where consistent edge life and predictable performance are required.\u003c\/p\u003e\n\u003cp\u003eThis insert fits KENLOC-series toolholders that accept CNMP-style negative-rake inserts held by clamp or pin. Primary workpiece materials are steel and cast iron, with the KCP25B grade also rated for aluminum and non-ferrous materials. The insert is suited to medium-depth roughing and semi-finishing passes in both horizontal and vertical turning centers. Four usable cutting edges per insert allow rotation before replacement, reducing per-edge tooling cost in high-production environments. The honed cutting edge style and negative rake geometry help control edge chipping when machining interrupted cuts or scaled surfaces.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eANSI CNMP431K \/ ISO CNMP120404K designation for direct cross-reference with toolholder catalogs\u003c\/li\u003e\n  \u003cli\u003eKCP25B grade with MTCVD multilayer TiCN \/ Al2O3 \/ TiOCN coating for wear resistance on steel and cast iron\u003c\/li\u003e\n  \u003cli\u003e80-degree diamond insert shape with 0-degree relief angle and negative rake for robust edge support\u003c\/li\u003e\n  \u003cli\u003eFour usable cutting edges per insert; neutral hand fits left- or right-hand toolholder setups\u003c\/li\u003e\n  \u003cli\u003e0.0156-inch corner radius (1\/64 inch) for a balance between surface finish and edge strength\u003c\/li\u003e\n  \u003cli\u003eMulti-use application: turning, facing, and boring from a single insert geometry\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for KENLOC-series toolholders accepting CNMP-style inserts with clamp or pin holding, as specified in the KENNAMETAL KENLOC toolholder system.

Ensure the toolholder pocket and seating surface are clean and free of chips before seating the insert. Confirm spindle and turret are at a full stop and machine is in an e-stop or lockout condition before changing inserts. Do not use inserts that show edge chipping, cratering, or built-up edge, as degraded edges increase cutting forces and risk workpiece damage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: CNMP431K\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: CNMP120404K\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KCP25B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN \/ Al2O3 \/ TiOCN (MTCVD Multilayer CVD)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: 80-Degree Diamond (Rhombic)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.5000 inches (1\/2 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 12.90 mm (0.5077 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.1875 inches (3\/16 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0156 inches (1\/64 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.1691 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.2031 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 0 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 10 degrees negative\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: Honed\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: Medium Machining (Common)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp and Pin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Cast Iron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: KENLOC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, ISO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0193 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1 insert per package\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: KENNAMETAL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5694095\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51748614668594,"sku":"5694095","price":180.1,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/80dc3503a38daec78ebcc978aa92502a_a0837943-ac03-424a-b911-d516cd8956d0.jpg?v=1788895747","url":"https:\/\/voomisupply.com\/products\/kennametal-5694095-turning-insert-cnmp431k-kcp25b-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
